Was trying for the last couple weeks to transfer from a standard world server to another standard world server (Midgarsormerr to Gilgamesh)

It will not allow me to choose Gilgamesh or Midgarsormerr as the destination.

I heard it might be restricted during times of congestion. Just trying to xfer to my friends server so we can play together. Any ideas suggestions or help would be appreciated.

What do you guys think?
